@gulfie You seem to have a similar system to my old one, though I had 32 gb of DDR3. The 3060ti WILL run on an older PCI-E 3.0 slot, but it will create SOMETHING of a bottleneck. That said, it won't be too noticable since sure while PCI-e 4.0 can do 64gb/s, HDMI 2.1 only does like... 48. so even then it won't use up all that bandwidth even if you had PCI-e 4.
